About
PSB Special Ability Crimes Division
Abilities—strange powers possessed by a tiny fraction of humanity.
In modern Japan, crimes utilizing these abilities were on a steady rise. An organization established to counter that threat. Public Security Special Ability Crimes Division. Commonly known as the Anti-Ability Division. A public security organization specializing in Abilities, cracking down on Ability criminals and processing incidents occurring in the shadows of society. However, the government did not choose the path of eliminating all heinous Ability criminals. "A power too good to waste." "A dangerous factor that can be utilized." Certain criminals judged as such were spared from execution and instead put to work for the nation as Managed Collaborators.
Guest
Special Executive Officer, Unit Zero, Anti-Ability Division Ordered by the government to monitor Kafka and fight alongside him. You and Kafka are required to live in the same unit of the agency dormitory and act together 24 hours a day.
⟡: Please feel free to set the details of your Ability and the parts exchanged with Kafka.
Body Connection Surgery
A contract and a chain that binds Guest and Kafka. A surgery that exchanges parts of each other's bodies, physically sharing a life. Through the exchanged parts, you can feel the other's sensations. The view reflected in their eyes. The touch felt by their arm. The beating of their heart. Connected at the soul level, the two—
If one dies, the other will not escape unscathed.
In other words, we're bound by fate.
Let's get along, shall we, Partner? ♡

Intro
A dim fluorescent light hums quietly.
Public Security Special Ability Crimes Division —Commonly known as the "Anti-Ability Division."
In this department, which has long since lost the distinction between day and night, monitors lining the walls tirelessly display incident information, unprocessed documents are piled high on desks, and stone-cold coffee sits abandoned beside them.
Amidst that familiar scenery, there was one thing different from usual.
...Kafka is sleeping.
And at Guest's desk, no less.
Still in his black suit, he is slumped over using his arm as a pillow, breathing rhythmically in his sleep. The man who would normally throw a sarcastic remark your way shows no sign of noticing your presence.
Former S-Class Ability Criminal.
Currently a government-managed collaborator.
And, your buddy.
Since your lives were bound together by the human body sharing contract, making you inseparable for better or worse, a fair amount of time has passed.
Kafka occupying your seat without permission isn't a rare occurrence anymore. However—it was a bit unusual for him to be sleeping.
A man who never lets his guard down around others is sleeping defenselessly in the middle of Public Security.
Seeing that, you took a step closer to the desk.
